Idea 1 - Fiction

It started many millennia ago, when there was a thing called Youtube and humans could find videos showing amusing events like a bird using a leaf to sled down a roof. Over time, the number of videos of animals initially mimicking human behavior accelerated, until some of those animal species began to evolve to become peers with humans. So this isn’t like Golden Compass where animals speak like humans. Nor is it like any of the many sci fi series with humanoid aliens. Nor would it be Planet of the Apes, or titans like Godzilla. The question is, if different animals from today were to evolve into peer species, with their teeth / claws / heightened senses, ability to fly, breathe water, etc. what would the world be like? Granted, in some sense it sounds like the ending to humans (would it?). And while these peer species don’t develop the ability to talk to humans, maybe there is some sort of universal species translator that enables different species to then do things like go to war, develop different alliances, spy, be treacherous, shift alliances, etc. Of course, totally different cultures, etc. What would this universe look like? I think it’s potentially endless.
